基于客货协同的地铁-货运系统设施规划研究

地铁-货运系统因其较低的工程投入和显著的社会及环境效益,被认为是当前城市地下物流的优先发展模式。本文针对地铁货运网络设施在“共线-分离”运作模式下的若干共性决策问题,提出系统性规划框架与原型设计方案。首先从节点通道设施分级、单元装箱策略、网络化运输流程和系统运行边界4个方面阐释了地铁客货协同机理;其次,基于“客货零干扰”、“自动化作业”、“地下空间节约”等原则,针对换乘地铁货运站点这类复杂设施,界定了10项站内基本功能模块和6项货流搬运业务;最后以南京地铁大行宫站为例,构建了“中岛-双侧式”地铁客货站台、站厅的3层地下功能区布置方案及配套物流作业方案,实现了站点整体配置的可视化。

Planning for the Metro-based Underground Logistics System Facility Based on Passenger-freight Collaboration

The Metro-based Underground Logistics System (M-ULS) is recognized as a preferential pattern for developing urban underground freight transport due to its low engineering investment and significant social -environmental benefits. This paper aims to propose a systematic planning and design protocol to solve the common issues regarding the decision-making of M-ULS network facilities under “collinear-detached” operation mode. Firstly, the mechanism of collaborative passenger-freight transport based on metro was analyzed from four aspects, i.e., (i) classification of nodes and channels in M-ULS network; (ii) unit encasement tactics; (iii) networked transportation process and (iv) system operational boundaries. Secondly, in line with principles, e.g., zero passenger-freight interference, automation and underground space use saving, a total of ten basic functional modules and six freight flow services equipped by a complex transferring metro freight station were defined. Finally, the Daxinggong Station of Nanjing Metro was taken as a case to build the three-layered underground functional area layout scheme and corresponding logistics operation scheme of the passenger-freight platforms and station hall with “middle island-two-sided” structure. The holistic configuration of metro freight station was visualized.
